Which type of refrigerant is generally used for household air conditioners?

At present, due to global warming, people use air conditioners more and more frequently, but not all users are familiar with the type and use of air conditioner refrigerants. Let us take a look at which air conditioner refrigerant to buy Best, what type of refrigerant is commonly used in household air conditioners?

Of course, R22 and r410a refrigerants are what everyone knows better about air-conditioning refrigerants, but because r22 has a certain destructive effect on the ozone layer, it is a transition Type refrigerant, and the later derived R410A refrigerant is also a widely used refrigerant type at present.

Comparison between R22 and R410A

R22 characteristics: colorless, almost odorless gas at room temperature, non-flammable, non-explosive, non-corrosive, and toxic Slightly larger than R12, but still a safe refrigerant, safety classification is A1; pressurized can be liquefied into a colorless and transparent liquid. R22 has high chemical and thermal stability, especially in the absence of water, it does not react with general metals below 200°C. In the presence of water, it only works slowly with alkali. However, cracking occurs at high temperatures. R22 is a kind of low-temperature refrigerant, which can get a cooling temperature of -80℃.

R410a is used in inverter air conditioners. It is a new type of environmentally friendly refrigerant that does not destroy the ozone layer, and its working pressure is about 1.6 times that of ordinary R22 air conditioners. It has high cooling (heating) efficiency and improves air conditioning performance without destroying the ozone layer.

R410a characteristics: R410a new refrigerant is composed of two quasi-azeotropic mixtures R32 and R125 each 50%, mainly composed of hydrogen, fluorine and carbon elements (expressed as hfc) , It has the characteristics of stability, non-toxicity and superior performance. At the same time, since it does not contain chlorine, it will not react with ozone, that is, it will not destroy the ozone layer. In addition, the performance of air conditioners using new refrigerants will also be improved. R410A is internationally recognized as the most suitable refrigerant to replace R22 so far, and it has been popularized in Europe, America, Japan and other countries. R410A replaces the global trends in major international markets and the outlook for its use and the dynamics of entering the international market.

The above is the relevant introduction of which model of household air conditioners are generally used. Note that the air conditioner refrigerant must be filled according to the model marked on the air conditioner, and avoid affecting the air conditioner system Cause damage, if you have any questions about the air-conditioning refrigerant model, you can consult and get more details on the use of the refrigerant model.
